Good luck, but I don't expect you'll find anything like a model, name or stats just yet. Ever since datamining started, Blizzard have been fairly successful in hiding their legendaries for a much longer time than other patch content. Unless my memory is faulty, Shadowmourne was actually first discovered when a Blizzard employee linked it on the 3.3 test realm.

Still, good work and good luck.

EDIT: Turns out I was way off. This is what happens when my mind goes wandering. Either way, great work.
